EIA/TIA-1154:2010

INTRODUCTION AND SCOPE This document specifies the requirements necessary to support MSC Pool in the CDMA2000®1 wireless network. MSC Pool enables signaling connections between one BSC with multiple MSCs, so the MS served by any BSC of that pool area can be served by any MSC in that pool area. MSC Pool is built upon to the Legacy Mobile Station Domain architecture. Serving Node Selection Function (SNSF) is the key functionality for MSC Pool application. The main function of SNSF is selecting a serving MSC within MSC Pool for a given user, and routing the signaling between the MSC and the BSC. 1 cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2.
